6RA70 → SINAMICS DCM
Modernising DC drives while keeping the DC motors
SIMOREG 6RA70 and other legacy DC drives are still found in many mills. We replace them with SINAMICS DCM or with stack controllers from Sprint or Gefran/WEG, reuse what can be reused, and keep the DC motors in service — in new cabinets built and tested in our facility.
What the migration covers
- Survey of existing DC drives and motors
- New two- or four-quadrant DC drive cabinets
- Integration into the existing PLC and network
